Patent number: 7597170Abstract: In a method for controlling the operation of a reversible belt retractor to release a belt extraction lock of a restraint belt in a motor vehicle, the lock can be activated by an acceleration sensor. After the belt retractor has been triggered as a consequence of a hazardous situation having been detected and after the hazardous situation has been recognized as being over, the operation of the belt retractor is controlled by a release signal at a release time in order to bring about the release of the belt extraction lock to shift it from a blocking state into a comfort-providing state. The release time is determined by a sensor model algorithm based on a model of the acceleration sensor from at least one variable characterizing the running dynamics.Type: GrantFiled: July 9, 2004Date of Patent: October 6, 2009Assignee: Daimler AGInventors: Ralf Bogenrieder, Walter Eberle, Rainer Justen, Hans Roehm, Guido Villino, Alfred Wagner, Markus Woldrich

Publication number: 20080109137Abstract: The invention relates to a method for actuating a reversible vehicle occupant protection means in a motor vehicle having a driving state sensor system and a reversible vehicle occupant protection means. The reversible vehicle occupant protection means can be triggered before the collision time and as a result moved into an effective position. For this purpose, the driving state data are monitored with respect to a state of emergency braking, and when the state of emergency braking is detected the vehicle occupant protection system is actuated. In addition, a state of oversteering and a state of understeering are determined by the data processing device. The reversible vehicle occupant protection system is actuated when the data processing device detects the state of emergency braking and/or the state of oversteering and/or the state of understeering.Type: ApplicationFiled: December 28, 2007Publication date: May 8, 2008Applicant: DAIMLER AGInventors: Walter EBERLE, Wolfgang HINRICHS, Rainer JUSTEN, Bernd MAMMEL, Hans ROEHM, Guido VILLINO, Markus WOLDRICH

Patent number: 7325641Abstract: Method for actuating a reversible belt pretensioner for pretensioning a belt webbing, unwound from a belt reel, of a seat belt in a motor vehicle, the belt pretensioner having a drive which acts on the belt reel, and the seat belt having, as a belt extraction lock, a locking device which acts on the belt reel in the unwinding direction and whose locking can be released only if the belt reel is rotated about a certain angle of rotation in the winding-on direction. After a triggering of the belt pretensioner caused by a hazardous situation and if a variable indicative of the belt force indicates a decrease in the belt force, an opening mode is initiated in which the belt pretensioner drive is actuated in order to open the blocking device in such a manner that, at the beginning of the opening mode, the belt reel rotates about the specific angle of rotation in the winding-on direction.Type: GrantFiled: October 31, 2002Date of Patent: February 5, 2008Assignee: DaimlerChrysler AGInventors: Wilfried Bullinger, Walter Eberle, Markus Woldrich

Patent number: 7100945Abstract: Method for actuating a reversible belt pretensioner for pretensioning a belt webbing, the belt pretensioner having a drive which acts on the belt reel, and the seat belt having, as a belt extraction lock, a locking device which acts on the belt reel in the unwinding direction and whose locking can be released only if the belt reel is rotated through a specific angle of rotation in the winding-on direction. After the triggering of the belt pretensioner, the drive of the belt pretensioner for opening the locking device is actuated in an opening mode such that firstly, in a winding-on phase, the belt reel rotates through the specific angle of rotation in the winding-on direction. In a subsequent holding phase, the drive of the belt pretensioner is actuated for a predefinable holding time TH such that the belt reel is held in its angular position.Type: GrantFiled: December 6, 2001Date of Patent: September 5, 2006Assignee: DaimlerChrysler AGInventors: Wilfried Bullinger, Walter Eberle, Markus Woldrich

Patent number: 6851716Abstract: A belt tightener of a seat belt in a vehicle, in particular a motor vehicle, is provided with a retracting spring in order to return the belt. A counterspring, which can be adjusted by a motor, is connected in parallel with the retracting spring in order to be able to reduce the tensile force of the belt for comfort considerations.

Patent number: 5523524Abstract: According to the state of the art, double chamber bass reflex boxes are constructed so that the housing is separated by a partition wall into two spaces (13, 14). A loudspeaker (19) is inserted into the partition wall. One of the two spaces (13, 14) is equipped with an outlet opening, into which a so-called bass reflex tube is inserted for tuning the box. If complicated housing shapes are to be manufactured, it is not possible to build the bass reflex tube and the wall to which it is connected, in one piece. In such instances it is rather necessary to insert the so-called bass reflex tube into an opening in the wall, and to attach it by means of suitable sealing and connecting means. For that reason the invention has the task of presenting a housing for double chamber bass reflex boxes (10) which is especially easy to produce.Type: GrantFiled: December 12, 1994Date of Patent: June 4, 1996Assignee: Nokia Technology GmbHInventors: Jorg Prokisch, Markus Woldrich
